Paper Abstract

Analyzing thermodynamic patterns during product development can easily be characterized by various "Modeling and Simulation" software programs to observe Emissive Signatures. Baseline temperatures are referenced as an adjusted "Blackbody" value and used to compare differential temperature changes during dynamometer testing. An infrared spectrum distinguishes pattern profiles unique to the product for both thermodynamic performance and to accurately validate test materials. A collaborative CRADA1 effort has been established between the US Army RDECOMTARDEC and Drive Dynamics LLC of Dallas, TX on the development of an advanced Run Flat Insert System for military wheeled vehicles. Mapping of measured infrared thermometer values help in locating and determining whether or not material temperatures are within design limits. Prior testing by the US Army Physical Simulation Team has established a baseline Emissive Signature for HMMWV wheel assemblies at specific loads and speeds. As advanced Run Flat Insert Systems are developed for increased load capacities using structurally engineered profiles the Emissive Signature can be used to compare to baseline wheel assemblies and aid in establishing Run Flat performance and longevity.
